されている。In the figure, 1 is a plate-like fin. Reference numerals 2, 2a, 2b, and 2c denote heat transfer tubes which are inserted into and closely attached to the plate-like fin 1, and through which the refrigerant flows. The plate-like fins 1 are cut linearly between rows in order to prevent heat transfer between the heat transfer tubes 2 having different temperatures between rows.
なお、伝熱管２は管外径ＤがＤ≦8.5mmで、列ピッチP
rと段ピッチPhとの比がPr/Ph≦0.7である。The heat transfer tube 2 has a tube outer diameter D ≦ 8.5 mm and a row pitch P
The ratio of r to the step pitch Ph is Pr / Ph ≦ 0.7.

に悪い。However, in the conventional configuration, the plate-like fin 1 is divided linearly between rows, and the outer diameter D of the heat transfer tube 2 is D ≦ 8.5 mm.
Since the ratio of the row pitch Pr to the step pitch Ph is Pr / Ph ≦ 0.7, the fin portion of the plate-like fin 1 in the row direction with respect to the heat transfer tube 2 is shorter than the fin portion in the step direction. Very inefficient.
また、段ピッチPhに対して、列ピッチPrを充分に大き
くしたならば、大型化及び、コストアップしてしまう。Further, if the row pitch Pr is made sufficiently large with respect to the step pitch Ph, the size and cost increase.
また、フィン効率を上げるために管径を大きくとれ
